    A new study of the X-shaped radio galaxy NGC , which will be published on February 20th in Astrophysics Journal, tries to explain their morphology and some of the featured associated with X- or Z-shaped radio galaxies. X-shaped galaxies are a class of extragalactic radio source that prominentl.   A: I study the smallest galaxies we know about.

A class of active galactic nuclei that probably represent the centers of radio galaxies whose jets happen to be pointed directly at us. dwarf spheroidal galaxy A subclass of dwarf elliptical galaxies that are round and diskless like other elliptical galaxies but are particularly small and much less bright.

The nuclei of most galaxies host supermassive black holes with millions or even billions of solar-masses of material. Material in the vicinity of such black holes can accrete onto a torus of dust and gas around the black hole, and when that happens the nuclei radiate powerfully across the full spectrum.

These active galactic nuclei (AGN) are among the most dramatic and interesting. Blueshifted absorption lines in the UV and X-ray spectra of active galaxies reveal the presence of massive outflows of ionized gas from their nuclei.

The “intrinsic” UV and X-ray absorbers show large global covering factors of the central continuum source, and the inferred mass loss rates are comparable to the mass accretion rates.

Many absorbers show variable ionic column densities, which Cited by: a. active galactic nuclei are produced by the merger of galaxies.

blazars are produced when material is ejected along the poles of a super massive black hole. quasars are produced when two galaxies merge to form a super massive black hole.

the center of the Milky Way and Andromeda galaxies contain super massive black holes. This new and expanded edition of Astrophysics of Galactic Nuclei, published by n inhas 3 completely new chapters - one considers nova and supernova remnants, the others discuss active galactic nuclei.

Galaxies attracted each other more strongly in the past because they were more massive; they had not yet turned most of their mass into stars and light.

Astronomy – Review sheet, Week 13 Other Galaxies KEY CONCEPT REVIEW When galaxies were first discovered, it was not clear that they lie far beyond the Milky Way until their variable stars were carefully observed • Debates about the nature of so-called.

The first Americans may have swept the Western Hemisphere and decimated its fauna within years. This book looks very much like another recent astronomy textbook by Seeds (Joseph R. Grundy Observatory), except that this one has some glorious images of galaxies and clusters and quite detailed explanations of binary and variable stars, star formation and classification, solar activity, the lives of galaxies, black holes, and cosmology Price: $ The study of extragalactic stellar populations thus began at the same time as cosmology, and classical novae have played a significant role in the study of populations ever since.

Novae are all binaries in which a white dwarf (WD) accretes matter from a hydrogen-rich brown dwarf, red dwarf or red giant companion, or helium from a WD companion.

A galaxy is a massive, gravitationally bound system consisting of stars, an interstellar medium of gas and dust, and dark matter. Typical galaxies range from dwarfs with as few as ten million.

Astronomers think that many galaxies, including our own Milky Way, have undergone similar collisions during their histories. Although the process of galaxy collision is important and common, what happens during these encounters is not very well understood.
